Abstract:

During August of 1993 the Bureau of Reclamation tested turbine aeration for dissolved oxygen (DO) enhancement at Deer Creek Powerplant near Provo, Utah. This test required a variety of instrumentation and equipment, assembled during a short time period prior to the tests. Objectives of the testing included determining the effectiveness of aeration, evaluating the impact on power output and mechanical behavior of the turbines, and obtaining data needed to design a permanent turbine aeration system. Variables of interest included standard powerplant parameters (head, discharge and power output), airflow parameters (pressure, temperature, and flowrate), water quality parameters (DO concentration and temperature), and mechanical parameters (shaft runout and bearing temperature). This paper will discuss the design of the tests and the instrumentation involved, as well as plans for additional testing during the implementation of turbine aeration at the site in the summer of 1994.
